Donald Trump, the bombastic billionaire who managed to galvanize millions while rending the Republican Party, is officially the GOP nominee for U.S. President.

The final vote Tuesday night at the Republican National Convention in Cleveland was 1,725 delegate votes for Trump, 475 votes for Texas Sen. Ted Cruz, 120 votes for Ohio Gov. John Kasich, who boycotted the convention, and 114 votes for Florida Sen. Marco Rubio.

The night was punctuated by small rebellions, with Ohio casting all 66 of its votes for Kasich and the Alaska delegation bringing the convention’s prime-time television coverage to a standstill with a protest over the way that state’s votes were allocated.

Eventually, after a brief interlude while party officials consulted their procedural guidebook, all of Alaska's 28 votes went to Trump, much to the consternation of the state delegate leader.

The Trump campaign was rocked by accusations that some of his wife's remarks were plagiarized from Michelle Obama's 2008 address at the Democratic National Convention.

The campaign denied stealing the first lady's remarks, saying Melania Trump had used common words to connect with American voters.

Trump adviser Sam Clovis said in an interview with MSNBC, "I'm sure what happened is the person who was helping write this plucked something in there and [it was] probably an unfortunate oversight - and certainly Melania didn't have anything to do with it."
